How much does beryllium copper cost?
The Platts Metals Week published prices for selected beryllium products were as follows: BCMA, $160 per pound of contained beryllium; beryllium copper alloy strip, $9.95 per pound; and beryllium copper casting ingot $6.40 per pound.
Is it safe to Machine beryllium copper?
Copper beryllium in solid form and as contained in finished products presents no special health risks. Most manufacturing operations, conducted properly on well-main- tained equipment, are capable of safely processing copper beryllium containing materials.
Why is beryllium added to copper?
Beryllium copper combines high strength with non-magnetic and non-sparking qualities. It has excellent metalworking, forming and machining properties. It has many specialized applications in tools for hazardous environments, musical instruments, precision measurement devices, bullets, and aerospace.
Is beryllium copper expensive?
Beryllium copper is expensive and weaker than alternatives like steel, but its non sparking property heightens its value. Compared to other alloys of similar strengths and durability, beryllium copper is very easily formable.
Is beryllium expensive?
BERYLLIUM IS A MATERIAL LIKE NO OTHER. Ninety-eight-percent pure beryllium is expensive, selling from $600 to $800 per pound prior to machining, so shops must understand its machining idiosyncracies to avoid scrapping progressively expensive parts.
Can beryllium be cut?
Cuts involving beryllium are no different than cuts from other metals. However, open wounds can be a pathway for small particles to enter the skin. As a good hygienic practice, wounds should be properly cleaned and bandaged and kept clean to aid the healing process.
Can beryllium be machined?
Beryllium is machined by all common metalworking processes; however, tapping can be difficult because of the high surface stresses involved and the lack of ductility of the material. If the machinablility factor of free-machining steel is rated at 100 percent, the machinability factor or beryllium is 55 percent.
Does beryllium copper tarnish?
Even when compared to other specialty copper alloys, beryllium copper ranks extremely high for its corrosion resistance. Items manufactured from beryllium copper do not tarnish easily, which is one of the reasons this alloy is highly sought after for electronic component manufacturing.
Is beryllium copper weldable?
Copper beryllium can be welded to itself, to other copper alloys, and to steels using appropriate RW techniques. Copper alloys less than 0.04 inch thick are generally easier to weld. The RW processes that are commonly applied to copper beryllium components are spot and projection welding.
Is beryllium copper flammable?
Specific Hazards Arising from the Material: This product does not present fire or explosion hazards as shipped. Small chips, fine turnings and dust from processing may be ignitable.
What is beryllium 25?
ASTM B196, AMS 4533, SAE J461, RWMA CLASS IV, CuBe2 2.1247 C17200 is also known as Alloy 25 and is the most commonly utilized beryllium copper alloy and is notable for exhibiting the highest strength and hardness compared to commercial copper alloys. Its strength and hardness is similar to that of steel.
What is high strength beryllium copper alloys?
High strength beryllium copper alloys contain 0.4 to 2% of beryllium with about 0.3 to 2.7% of other alloying elements such as nickel, cobalt, iron or lead. The high mechanical strength is achieved by precipitation hardening or age hardening.
What is the typical size of C17200 beryllium copper?
Typical Uses for C17200 Beryllium Copper: Sizes Available From NBM SOLID BAR: 1/4″. 6″ diameter RECTANGLES: 3/8″ x 1/2″. 1″ x 3″ thickness x width
What is the solubility of beryllium in copper at room temperature?
The solubility of beryllium in copper increases with increasing temperature, from practically zero at room temperature to more than 2% by weight at temperatures above 800°C. This zone is represented at the left of the diagram where the alloy is in solid solution (phase ), a face centred cubic structure like copper.
